First instance option parses post title

Have been using this great plugin for some time. Recently, it’s been parsing the post titles and counting the terms as first entries, but not underlining them. That’s fine, but the problem is that the first instances of the terms in the post aren’t getting highlighted, so it is effectively inoperable.

The terms that the noted post are referencing are Triangulation and Neoliberalism.

Thanks for the help,

Tyler
